"We think it's too early to react to the 25 percent proposal," Mark Nixon, spokesperson for the Lansing Board of Water & Light, said Thursday. "But the BWL is confident it will meet or exceed the 10 percent renewable standard which is currently state law."

The BWL became the first utility in the state to adopt its own RPS in 2007, setting a goal for the company to acquire 7 percent of its power from renewable energy by 2016.

State legislation enacted in 2008 required all utilities to get 10 percent of their energy from renewable sources by 2015.

Nixon said the utility powers 10,000 Greater Lansing homes using methane captured from the Granger landfill in Lansing. It also boasts one of the largest solar arrays in the state, and has a "modest" hydro-power operation.

Additionally, Nixon said the BWL's new cogeneration plant will be equipped with some renewables like solar and wind turbines.
